| 1 | Dendritic Cells Transduced with SOCS1 Gene Exhibit Regulatory DC Properties and Prolong Allograft Survival显示文摘SOCS1 is a key regulator of cytokine signaling and is important for maintaining balance in the immune system. It is thought to participate in negative feedback loops in cytokine signaling and may be an important signal for the regulation of dendritic cell (DC) maturation. However, it remains unclear whether DCs transduced with SOCS1 exhibit characteristics of regulatory DCs and induce allogeneic T-cell hyporesponsiveness. In this study, we constructed adenoviral vector coding SOCS1 (Ad-SOCS1) that can efficiently increase SOCS1 gene expression in bone marrow-derived dendritic cells. DCs transduced with Ad-SOCS1 (DC-SOCS1) expressed low levels of costimulatory and MHC molecules, were resistant to maturation and activation stimulation, induced allogeneic T-cell hyporesponsiveness, and promoted the generation of regulatory-like T cells in vitro. DC-SOCS1 pretreatment significantly prolonged the survival of allografts and led to a substantial increase in the generation of regulatory T cells. Our data suggest that SOCS1 inhibits DC maturation and induces regulatory DC generation, therefore possessing therapeutic potential to prevent rejection in organ transplantation. | Hong Fu Shaohua Song Fang Liu Zhijia Ni Xiaoyun Shen Liang Xiao Guoshan Ding Quanxing Wang | 2009 | Cellular & Molecular Immunology2009，6，2： | 20 |
| 2 | Characteristics and Source Identification of Polycyclic Aromatic Hydrocarbons (PAHs) in Urban Soils: A Review显示文摘Polycyclic aromatic hydrocarbons(PAHs) are mainly produced by combustion processes and consist of a number of toxic compounds.They are always emitted as a mixture and have become a major type of pollutants in urban areas.The degree of soil contamination by PAHs is of special concern in areas immediately in proximity to cities with heavy traffic,factories,older buildings,and infrastructure.The accumulation of soil PAHs is also affected by non-anthropogenic factors,such as climate,vegetation,and soil property.This paper reviews three typical source identification techniques,including diagnostic ratios,positive matrix factorization,and principle components analysis.The advantages or disadvantages of these techniques are analyzed.It is recommended that multiple identification techniques be used to determine the sources in order to minimize the weaknesses inherent in each method and thereby to strengthen the conclusions for PAH source identification. | WANG Chunhui WU Shaohua ZHOU Shenglu SHI Yaxing SONG Jing | 2017 | Pedosphere2017，27，1： | 18 |
| 3 | ^(15)N isotope fractionation in an aquatic food chain:Bellamya aeruginosa(Reeve) as an algal control agent显示文摘15N isotope tracer techniques and ecological modeling were adopted to investigate the fractionation of nitrogen,its uptake and transformation in algae and snail(Bellamya aeruginosa Reeve).Different algal species were found to differ in their uptake of nitrogen isotopes.Microcystis aeruginisa Ktz.demonstrated the greatest 15N accumulation capacity,with the natural variation in isotopic ratio(δ 15N) and the isotope fractionation factor(ε,‰) being the highest among the species investigated.The transformation and utilization of 15N by snails differed depending on the specific algae consumed(highest for Chlorella pyrenoidosa Chick.,lowest for M.aeruginisa).When snails was seeded in the experimental pond,the algae population structure changed significantly,and total algal biomass as well as the concentration of all nitrogen species decreased,causing an increase in water transparency.A model,incorporating several chemical and biological parameters,was developed to predict algal biomass in an aquatic system when snails was present.The data collected during this investigation indicated that the gastropods such as snails could significantly impact biological community and water quality of small water bodies,suggesting a role for biological control of noxious algal blooms associated with eutrophication. | Shiqun Han Shaohua Yan Kaining Chen Zhenhua Zhang Rengel Zed Jianqiu Zhang Wei Song Haiqin Liu | 2010 | Journal of Environmental Sciences2010，22，2： | 14 |

| 5 | 对“东亚共同体”建设的再思考(英文)显示文摘在美国高调“重返亚洲”、日本加速“右倾化”、东亚国家岛屿与海洋权益争端日趋激化等因素作用下,东亚合作困难增多,深化发展面临瓶颈。虽然“东亚共同体”构想在现阶段受到一定质疑,但其在引领东亚合作进程中发挥了重要作用,仍具有强大的生命力。中国应坚定支持“东亚共同体”建设,并为其赋予新的内涵,探索新的路径。中国新领导集体的外交理念对“东亚共同体”建设具有重要启示作用。 | Song Junying Yu Shaohua | 2014 | 国际问题研究2014，，2： | 7 |
| 6 | Evolution of Tectonic Uplift, Hydrocarbon Migration, and Uranium Mineralization in the NW Junggar Basin: An Apatite Fission-Track Thermochronology Study显示文摘The Mesozoic–Cenozoic tectonic movement largely controls the northwest region of the Junggar Basin(NWJB), which is a significant area for the exploration of petroleum and sandstone-type uranium deposits in China. This work collected six samples from this sedimentary basin and surrounding mountains to conduct apatite fission track(AFT) dating, and utilized the dating results for thermochronological modeling to reconstruct the uplift history of the NWJB and its response to hydrocarbon migration and uranium mineralization. The results indicate that a single continuous uplift event has occurred since the Early Cretaceous, showing spatiotemporal variation in the uplift and exhumation patterns throughout the NWJB. Uplift and exhumation initiated in the northwest and then proceeded to the southeast, suggesting that the fault system induced a post spread-thrust nappe into the basin during the Late Yanshanian. Modeling results indicate that the NWJB mountains have undergone three distinct stages of rapid cooling: Early Cretaceous(ca. 140–115 Ma), Late Cretaceous(ca. 80–60 Ma), and Miocene–present(since ca. 20 Ma). These three stages regionally correspond to the LhasaEurasian collision during the Late Jurassic–Early Cretaceous(ca. 140–125 Ma), the Lhasa-Gandise collision during the Late Cretaceous(ca. 80–70 Ma), and a remote response to the India-Asian collision since ca. 55 Ma, respectively. These tectonic events also resulted in several regional unconformities between the J3/K1, K2/E, and E/N, and three large-scale hydrocarbon injection events in the Piedmont Thrust Belt(PTB). Particularly, the hydrocarbon charge event during the Early Cretaceous resulted in the initial inundation and protection of paleo-uranium ore bodies that were formed during the Middle–Late Jurassic. The uplift and denudation of the PTB was extremely slow from 40 Ma onward due to a slight influence from the Himalayan orogeny. However, the uplift of the PTB was faster after the Miocene, which led to re-uplift and exposure at the surface during the Quaternary, resulting in its oxidation and the formation of small uranium ore bodies. | QIN Mingkuan HUANG Shaohua HE Zhongbo XU Qiang SONG Jiye LIU Zhangyue GUO Qiang | 2018 | Acta Geologica Sinica(English Edition)2018，92，5： | 7 |
| 7 | Optimal yield-related attributes of irrigated rice for high yield potential based on path analysis and stability analysis显示文摘Improvement of yield in rice(Oryza sativa L.) is vital for ensuring food security in China. Both rice breeders and growers need an improved understanding of the relationship between yield and yield-related traits. New indica cultivars(53 in 2007 and 48 in 2008) were grown in Taoyuan,Yunnan province, to identify important components contributing to yield. Additionally, two standard indica rice cultivars with similar yield potentials, II You 107(a large-panicle type) and Xieyou 107(a heavy-panicle type), were planted in Taoyuan, Yunnan province and Nanjing,Jiangsu province, from 2006 to 2008 to evaluate the stability of yield and yield-related attributes.Growth duration(GD), leaf area index(LAI), panicles per m2(PN), and spikelets per m2(SM) were significantly and positively correlated with grain yield(GY) over all years. Sequential path analysis identified PN and panicle weight(PW) as important first-order traits that influenced grain yield. All direct effects were significant, as indicated by bootstrap analysis. Yield potential varied greatly across locations but not across years. Plant height(PH), days from heading to maturity(HM), and grain weight(GW) were stable traits that showed little variation across sites or years, whereas GD(mainly the pre-heading period, PHP) and PN varied significantly across locations. To achieve a yield of 15 t ha-1, a cultivar should have a PH of 110–125 cm, a long GD with HM of approximately 40 days, a PN of 300–400 m-2, and a GW of 29–31 mg. | Ganghua Li Jun Zhang Congdang Yang Yunpan Song Chengyan Zheng Shaohua Wang Zhenghui Liu Yanfeng Ding | 2014 | The Crop Journal2014，2，4： | 4 |
| 8 | Multi-agent system application in accordance with game theory in bi-directional coordination network model显示文摘The multi-agent system is the optimal solution to complex intelligent problems. In accordance with the game theory, the concept of loyalty is introduced to analyze the relationship between agents' individual income and global benefits and build the logical architecture of the multi-agent system. Besides, to verify the feasibility of the method, the cyclic neural network is optimized, the bi-directional coordination network is built as the training network for deep learning, and specific training scenes are simulated as the training background. After a certain number of training iterations, the model can learn simple strategies autonomously. Also,as the training time increases, the complexity of learning strategies rises gradually. Strategies such as obstacle avoidance, firepower distribution and collaborative cover are adopted to demonstrate the achievability of the model. The model is verified to be realizable by the examples of obstacle avoidance, fire distribution and cooperative cover. Under the same resource background, the model exhibits better convergence than other deep learning training networks, and it is not easy to fall into the local endless loop.Furthermore, the ability of the learning strategy is stronger than that of the training model based on rules, which is of great practical values. | ZHANG Jie WANG Gang YUE Shaohua SONG Yafei LIU Jiayi YAO Xiaoqiang | 2020 | Journal of Systems Engineering and Electronics2020，31，2： | 3 |
| 9 | Multistage Enrichment of the Sawafuqi Uranium Deposit: New Insights into Sandstone-hosted Uranium Deposits in the Intramontane Basins of Tian Shan, China显示文摘Meso-Cenozoic intracontinental orogenic processes in the Tian Shan orogenic belt have significant effect on the sandstone-hosted uranium deposits in the intramontane basins and those adjacent to the orogen. The Sawafuqi uranium deposit, which is located in the South Tian Shan orogenic belt, is investigated to reveal the relationships between uranium mineralization and orogenies. Recent exploration results show that the Sawafuqi uranium deposit has tabular, stratiform, quasi-stratiform, and lens-like orebodies and various geological characteristics different from typical interlayer oxidation zone sandstone-hosted uranium deposits. Systematic studies of ore samples from the Sawafuqi uranium deposit using a variety of techniques, including thin section observation, α-track radiograph, electron microprobe and scanning electron microscope, suggest that uranium mineralization is closely related to pyrite and organic matter. Mineralization-related alterations in the host rocks are mainly silicification and argillation including kaolinite, illite(and illite-smectite mixed layer) and chlorite. Tree stages of mineralization were identified in the Sawafuqi uranium deposit:(i) uranium-bearing detritus and synsedimentary initial pre-enrichment;(ii) interlayer oxidization zone uranium mineralization; and(iii) vein-type uranium mineralization. The synsedimentary uranium pre-enrichment represents an early uranium enrichment in the Sawafuqi uranium deposit, and interlayer oxidation zone uranium mineralization formed the main orebodies, which are superimposed by the vein-type uranium mineralization. Combining the results of this study with previous studies on the Meso-Cenozoic orogenies of South Tian Shan, it is proposed that the synsedimentary uranium pre-enrichment of the Sawafuqi uranium deposit was caused by Triassic Tian Shan uplift, and the interlayer oxidation zone uranium mineralization occurred during the Eocence-Oligocene period, when tectonism was relatively quiet, whereas the vein-type uranium mineralization took place in relation to the strong orogeny of South Tian Shan since Miocene. | LIU Zhangyue PENG Suping QIN Mingkuan LIU Hongxun HUANG Shaohua HE Zhongbo GUO Qiang XU Qiang SONG Jiye | 2017 | Acta Geologica Sinica(English Edition)2017，91，6： | 3 |
| 10 | Implementation of One-Way Quantum Computing with a Hybrid Solid-State Quantum System显示文摘We proposed an efficient scheme for implementing the large-scale one-way Quantum computing(QC)with a novel hybrid solid-state quantum system.

| 11 | Highly efficient luminescent Ⅰ-Ⅲ-Ⅵ semiconductor nanoprobes based on template-synthesized CuInS2 nanocrystals显示文摘CuInS2 semiconductor nanocrystals (NCs) exhibit large absorption coefficient, size-dependent photoluminescence and low toxicity, making them excellent candidates in a variety of bioapplications. However, precise control of both their composition and morphology to improve the luminescent efficiency remains a great challenge via conventional direct synthesis. Herein, we present a novel low-temperature template synthesis of highly efficient luminescent CuInS2 nanoprobes from In2S3 NCs via a facile cation exchange strategy. The proposed strategy enables synthesis of a series of CuInS2 NCs with broad size tunability from 2.2 to 29.6 nm. Through rationally manipulating the stoichiometry of Cu/In, highly efficient luminescence of CuInS2 with the maximum quantum yield of 28.6% has been achieved, which is about one order of magnitude improvement relative to that of directly synthesized NCs. By virtue of the intense emission of CuInS2 nanoprobes, we exemplify their application in sensitive homogeneous biodetection for an important biomolecule of adenosine triphosphate (ATP) with the limit of detection down to 49.3 nM. Moreover, the CuInS2 nanoprobes are explored for ATP-targeted cancer cell imaging, thus revealing their great potentials in the field of cancer diagnosis and prognosis. | Xian Li Datao Tu Shaohua Yu Xiaorong Song Wei Lian Jiaojiao Wei Xiaoying Shang Renfu Li Xueyuan Chen | 2019 | Nano Research2019，12，8： | 3 |
| 12 | Burden of pancreatitis and associated risk factors in China,1990 to 2019:a systematic analysis for the Global Burden of Disease Study 2019显示文摘Background: Pancreatitis is a common disease of the digestive system. Acute pancreatitis is one of the most common reasons for gastrointestinal hospital admission, and chronic pancreatitis significantly reduces quality of life. However, national epidemiological data on pancreatitis in China are lacking. This study aimed to quantify the disease burden of pancreatitis in China from 1990 to 2019.Methods: This study was based on the Global Burden of Disease Study 2019 dataset. Age-standardized rates of incidence (ASIR), prevalence (ASPR), mortality (ASMR), and disability-adjusted life years (DALYs) were used to describe the disease burden of pancreatitis, and estimated annual percentage change (EAPC) was used to indicate the average change in age-standardized rates. We also described the trend of pancreatitis-related mortality and DALYs, which are attributable to alcohol use by age and sex.Results: From 1990 to 2019, the ASIR, ASPR, ASMR, and age-standardized DALYs of pancreatitis in China decreased by 10.90, 1.50, 0.49, and 15.54 per 100,000, respectively, with EAPCs of -1.35 (95% uncertainty interval [UI]: -1.67, -1.02) and -0.37 (95% UI: -0.43, -0.31), -2.01 (95% UI: -2.07, -1.94) and -2.32 (95% UI: -2.37, -2.28), respectively. Recently, the numbers of incident and prevalent cases have risen, with estimates of 380,018 (95% UI: 308,669-462,767) and 493,765 (95% UI: 416,705-578,675), respectively, in 2019. Among men, the disease burden of pancreatitis was more severe than among women, and with variances in the distribution among different age groups. Age-standardized DALYs caused by alcohol-related pancreatitis have gradually worsened in the past decade, accounting for 34.09% of the total in 2019.Conclusions: The disease burden of pancreatitis in China has declined in the past 30 years, but the exacerbation of population aging poses a challenge to prevention and control of pancreatitis. Alcohol use has gradually become an important factor in the disease burden of pancreatitis in recent years. | Ke Han Shimin Chen Yang Song Chen Du Fei Gao Shaohua Liu Yao He Ningli Chai Enqiang Linghu Miao Liu | 2022 | Chinese Medical Journal2022，，11： | 3 |

| 14 | A survey of remote sensing image classification based on CNNs显示文摘With the development of earth observation technologies,the acquired remote sensing images are increasing dramatically,and a new era of big data in remote sensing is coming.How to effectively mine these massive volumes of remote sensing data are new challenges.Deep learning provides a new approach for analyzing these remote sensing data.As one of the deep learning models,convolutional neural networks(CNNs)can directly extract features from massive amounts of imagery data and is good at exploiting semantic features of imagery data.CNNs have achieved remarkable success in computer vision.In recent years,quite a few researchers have studied remote sensing image classification using CNNs,and CNNs can be applied to realize rapid,economical and accurate analysis and feature extraction from remote sensing data.This paper aims to provide a survey of the current state-of-the-art application of CNN-based deep learning in remote sensing image classification.We first briefly introduce the principles and characteristics of CNNs.We then survey developments and structural improvements on CNN models that make CNNs more suitable for remote sensing image classification,available datasets for remote sensing image classification,and data augmentation techniques.Then,three typical CNN application cases in remote sensing image classification:scene classification,object detection and object segmentation are presented.We also discuss the problems and challenges of CNN-based remote sensing image classification,and propose corresponding measures and suggestions.We hope that the survey can facilitate the advancement of remote sensing image classification research and help remote-sensing scientists to tackle classification tasks with the state-of-art deep learning algorithms and techniques. | Jia Song Shaohua Gao Yunqiang Zhu Chenyan Ma | 2019 | Big Earth Data2019，3，3： | 3 |
| 15 | Upconversion Luminescence Properties and Mechanism of Er^(3+) Doped Ba_(0.65)Sr_(0.35)TiO_3 Ferroelectric Oxide Nanocrystals显示文摘Ba0.65Sr0.35TiO3(BST) nanocrystals doped with different concentrations of Er3+ ion were fabricated using sol-gel method. The structure and morphology of these BST nanocrystals were studied using X-ray diffraction(XRD), field emission scanning electron microscopy(FESEM) and transmission electron microscopy(TEM). The X-ray diffraction patterns of all the nanocrystals prepared in the study correspond to polycrystalline perovskite BST structure. The blue and green upconversion luminescence properties of Er3+ doped BST nanocrystals were investigated under excitation by a 785-nm laser. The upconversion emission bands centered at 407, 523, and 547 nm can be attributed to 2H9/2, 4I15/2, 2H11/2, 4I15/2, and 4S3/2, 4I15/2 transitions of Er3+ ion, respectively. The upconversion mechanism was studied in detail, based on the laser power dependence of the upconverted emissions. In addition, we examined the dependence of the intensity of green upconverted luminescence on the doping concentration of Er3+ ions, and discussed the mechanism underlying the process. | 汪竞阳 ZHANG Tianjin QU Shaohua ZHONG Zhicheng WANG Song | 2015 | Journal of Wuhan University of Technology(Materials Science)2015，30，2： | 2 |

| 17 | Current status,trends,and predictions in the burden of gallbladder and biliary tract cancer in China from 1990 to 2019显示文摘Background:Gallbladder and biliary tract cancer(GBTC)has greatly damaged the health of patients and is accompanied by a dismal prognosis.The worldwide distribution of GBTC shows extensive variance and the updated data in China is lacking.This study was to determine the current status,trends,and predictions in the burden of GBTC over the past 30 years in China.Methods:This was a descriptive,epidemiological,secondary analysis of the Global Burden of Disease,Injuries,and Risk Factor Study 2019 data.Data including incidence,prevalence,mortality,and disability-adjusted life years(DALYs)of GBTC in China by year,age,and sex were assessed.Joinpoint regression analysis was conducted to evaluate trends of disease burden due to GBTC from 1990 to 2019.Nordpred age-period-cohort analysis was applied for the projection of mortality and incidence due to GBTC from 2019 to 2044.Results:Nationally,there were 38,634(95%uncertainty interval[UI]:27,350-46,512)new cases and 47,278(95%UI:32,889-57,229)patients due to GBTC,causing 34,462(95%UI:25,220-41,231)deaths,and 763,584(95%UI:566,755-920,493)DALYs in 2019.Both cases and rates of burden owing to GBTC were heavier among males and at old age.From 1990 to 2019,the age-standardized rates of incidence,prevalence,mortality,and DALYs of GBTC generally increased from 1990 to 2019,with average annual percentage change at 0.8%(95%confidential interval[CI]:0.6-1.0%),1.3%(95%CI:1.1-1.5%),0.4%(95%CI:0.2-0.6%),and 0.2%(95%CI:0.1-0.4%),respectively.Even though the age-standardized incidence rate and agestandardized mortality rate in both sexes were predicted to decline gradually from 2019 to 2044,the number of new cases and deaths were expected to grow steadily.Conclusions:GBTC is becoming a major health burden in China,particularly among males and older individuals.Given the aging population and increasing burden,effective strategies and measurements are urged to prevent or reduce the number of new cases and deaths of GBTC. | Shimin Chen Ke Han Yang Song Shaohua Liu Xuehang Li Shengshu Wang Haowei Li Rongrong Li Jianhua Wang Yao He Miao Liu | 2022 | Chinese Medical Journal2022，，14： | 2 |
| 18 | Low threshold random lasing in dye-doped and strongly disordered chiral liquid crystals显示文摘Random lasing was experimentally investigated in pyrromethene 597-doped strongly disordered chiral liquid crystals (CLCs) composed of the nematic liquid crystal SLC1717 and the chiral agent CB15. The concentration of the chiral agent tuned the bandgap, and disordered CLC microdomains were achieved by fast quenching of the mixture from the isotropic to the cholesteric phase. Random lasing and band edge lasing were observed synchronously, and their behavior changed with the spectral location of the bandgap. The emission band for band edge lasing shifted with the change of the bandgap, while the emission band for random lasing remained practically constant. The results show that the threshold for random lasing sharply decreases if the CLC selective reflection band overlaps with the fluorescence peak of the dye molecules and if the band edge coincides at the same time with the excitation wavelength. | SHAOHUA GAO JIAYI WANG WENHUA LI XUANYI YU XINZHENG ZHANG XIAO SONG ANDREY ILJIN IRENA DREVENSEK-OLENIK ROMANO A.RUPP JINGJUN XU | 2020 | Photonics Research2020，8，5： | 2 |
| 19 | Mesozoic Tectonothermal Evolution of the Southern Central Asian Orogenic Belt: Evidence from Apatite Fission-Track Thermochronology in Shalazha Mountain, Inner Mongolia显示文摘Mesozoic intracontinental orogeny and deformation were widespread within the southern Central Asian Orogenic Belt(CAOB). Chronological constraints remain unclear when assessing the Mesozoic evolution of the central segment of this region. The tectonic belt of Shalazha Mountain located in the center of this region is an ideal place to decode the deformation process. Apatite fission-track(AFT) thermochronology in Shalazha Mountain is applied to constrain the Mesozoic tectonothermal evolution of the central segment of southern CAOB. The bedrock AFT ages range from 161.8 ± 6.9 to 137.0 ± 7.3 Ma, and the first reported detrital AFT obtained from Lower Cretaceous strata shows three age peaks: P1(ca. 178 Ma), P2(ca. 149 Ma) and P3(ca. 105.6 Ma). Bedrock thermal history modeling indicates that Shalazha Mountain have experienced three stages of differential cooling: Late Triassic–Early Jurassic(~230–174 Ma), Late Jurassic–Earliest Cretaceous(~174–135 Ma) and later(~135 Ma). The first two cooling stages are well preserved by the detrital AFT thermochronological result(P1, P2) from the adjacent Lower Cretaceous strata, while P3(ca. 105.6 Ma) records coeval volcanic activity. Furthermore, our data uncover that hanging wall samples cooled faster between the Late Triassic and the Early Cretaceous than those from the footwall of Shalazha thrust fault, which synchronizes with the cooling of the Shalazha Mountain and implies significant two-stage thrust fault activation between ca. 230 and 135 Ma. These new low-temperature thermochronological results from the Shalazha Mountain region and nearby reveal three main phases of differential tectonothermal events representing the Mesozoic reactivation of the central segment of the southern CAOB. In our interpretations, the initial rapid uplift in the Late Triassic was possibly associated with intracontinental orogenesis of the CAOB. Subsequent Middle Jurassic–Earliest Cretaceous cooling is highly consistent with the Mesozoic intense intraplate compression that occurred in the southern CAOB, and is interpreted as a record of closure of the Mongol-Okhotsk Ocean. Then widespread Cretaceous denudation and burial in the adjacent fault basin could be linked with the oblique subduction of the Izanagi Plate along the eastern Eurasian Plate, creating a northeast-trending normal fault and synchronous extension. However, our AFT thermochronometry detects no intense Cenozoic reactivation information of Shalazha Mountain region. | Heng Peng Jianqiang Wang Chiyang Liu Shaohua Zhang Yazhuo Niu Tianbing Zhang Bo Song Wei Han | 2023 | Journal of Earth Science2023，34，1： | 1 |
